New discoveries, the scientific method, and all matters relating to the scientific study of the physical world
Even with my cheap 8 x 25 binoculars, the moon is impressive on a cold, clear night. You can get quite a sense of its differing terrain and three-dimensional character. It may be an illusion, but it even seems barely possible to make out that Venus is a crescent rather than a point.
It would be really interesting to try out a pair of image stabilized 15 x 80 binoculars. With those, you could see a lot more detail – especially if you could get away from city lights.
Previously, I described an asymmetry between the approach of climate change deniers and climate scientists, with the latter unwilling to retract any claims no matter how poorly justified or effectively rebutted. I think the instance with the IPCC and ‘poorly substantiated’ Himalayan glacier data is illustrative.
A failure to properly vet some information has come to light, and the IPCC has responded in an open and honest way:
In drafting the paragraph in question, the clear and well-established standards of evidence, required by the IPCC procedures, were not applied properly…
The Chair, Vice-Chair, and Co-Chairs of the IPCC regret the poor application of well-established IPCC procedures in this instance. This episode demonstrates that the quality of the assessment depends on absolute adherence to the IPCC standards, including thorough review of ‘the quality and validity of each source before incorporating results from the source in an IPCC report.
Climate deniers have jumped on all this to argue that it undermines the overall conclusions reached by the IPCC. Far from calling into question the overall scientific consensus, this willingness to concede errors demonstrates one of the reasons for which it is robust, namely a willingness to accept and respond to valid criticism. By contrast, deniers of various stripes tend to rub along well with one another, even when they have wildly different positions: that climate change isn’t happening, that it is actually beneficial, that it is caused by something other than greenhouse gases, etc.
I have written before about how the certification of a fishery by the Marine Stewardship Council is not sufficient cause to think it is genuinely sustainable (even before factors other than fish numbers, such as fossil fuel use by ships, are taken into account). More evidence for this has been forthcoming recently. Now, they have decided to certify the British Columbia sockeye salmon fishery, despite how the fish numbers are dwindling and subject to an ongoing inquiry. Last year’s run on the Fraser river was less than 10% of what had been expected. The recent history of salmon in BC is a catalog of failure. The decision to certify regardless certainly doesn’t leave the MSC looking very credible. Their decision doesn’t become official until a 15-day complaint period has concluded, and people will hopefully be able to persuade them to think differently during that span.
For those who really care about environmental issues and are willing to make personal choices to reflect that, I recommend avoiding fish (and other sorts of meat) entirely. Keeping fishing activity at a sustainable level just seems to require more political integrity and long-term thinking than any of the world’s governments can muster. It’s so much easier to grab a haul now, earn a bundle, and leave the mess for those who will come later.
Here’s a neat idea: a protective expandable honeycomb cushion for helicopters. They are rather dangerous machines, compared with fixed-wing aircraft, so anything that reduces the lethality of crashes would be welcome. Apparently, a test was conducted with a helicopter going 53 km/h and falling over 10m. Not only did the crash test dummies indicate that the accident would have been survivable for those inside, but the helicopter was in good enough shape to repair for a second trial.
The failure of Copenhagen and other climate change setbacks raise the real possibility that the world will continue to obsess over trivialities, missing the big picture until it is too late to prevent radical change. As such, we need to at least contemplate the possibility of seeing more than 4˚C of mean global temperature rise within our lifetimes, with all the radical effects that might accompany that.
As individuals, what kind of strategies could permit that? Warming is likely to be far more pronounced in the higher latitudes than in more temperate ones. Sea levels are likely to rise significantly, while summer snowpack and glaciers are likely to vanish. Crops that have been well suited to regions for all of human history may no longer grow where they used to. How can someone with no intention of having children maximize their odds of living decently in a world we are so actively undermining? What should those who have reproduced (or are considering doing so) take into consideration, above and beyond that?
For the sake of this planning exercise, it is worth considering outcomes that are plausible and serious, even if they are more unlikely than likely. After all, there are a lot of powerful feedback mechanisms that haven’t yet been incorporated into climate models. It is also worth remembering that even business-as-usual projections, based on emissions continuing to grow at the present rate, involve projected warming of over 5˚C by the end of the century, making the planet far hotter than at any time in human history.
Note that this has been partly discussed here before.
One curious thing about those who are determined to avoid the emergence of effective climate change policies is how they argue that climate science is far too uncertain to serve as the basis for decision-making, while simultaneously claiming that their economic models prove that going low-carbon will produce certain economic ruin. That claim is especially poorly defended over the long-term, given that economic models cannot effectively incorporate the consequences of technology and capital changes across a span of decades. Also, the idea that fossil fuel based prosperity will be everlasting faces a fundamental challenge from the scarcity of those fuels, and the political volatility of many of the regions in which they are found.
Near-term data also suggests that Canadian companies can cut emissions without suffering economic ruin. According to Tyler Hamilton’s blog:
[Canada’s] Top 10 industrial CO2 emitters reduced their greenhouse gas emissions by 9 per cent in 2008 compared to 2007. At the same time, the Canadian economy grew by 0.5 per cent. Given that the impacts of the economic downturn were felt mostly in 2009, an even greater drop is expected this year. Canada’s Top 350 emitters reduced greenhouse gas emissions by nearly 6 per cent during the same period.
Of course, that does not prove, in and of itself, that effective climate change policies would be painless in terms of costs or jobs. Still, just as the onus must be on climate scientists to both refine their models and acknowledge their limitations, those who assert that good climate policies will be economically ruinous must address both evidence and arguments that suggest that this may not be so.
A flawed but interesting blog post about climate change and conspiracy theories does a good job of summing up what climate change deniers are actually alleging:
They argue that the governments of Europe, of the US, of Canada, of China and India, and indeed of much of the rest of the world–governments that rarely agree on anything, I might point out–are acting in concert to promote a bogus claim that the earth is heating up because of man-made release of carbon dioxide into the atmosphere. They claim that this conspiracy is being supported by the almost universal connivance of the world’s scientists, who are collectively falsifying data and hiding countervailing data. And all this is happening, they assert, despite the almost universal opposition of the world’s corporations, most of which, we know, are resisting having governments take any serious action to combat climate change, and in many cases (look at the US Chamber of Commerce), are actively challenging the whole notion of climate change.
When put that way, it really doesn’t sound terribly plausible. Of course, there will be new developments in science as we refine our models and collect more data about what is actually happening in the world. That is simply a consequence of the nature of the climate system and of scientific inquiry. To argue, however, that the world’s scientific and political community are cooperating to actively mislead people into thinking there is a problem where none actually exists is quite preposterous.
Note that I called the post ‘flawed but interesting’ because it contains a number of dubious claims not related to climate change – for instance, that only a fire hot enough to melt steel could explain the catastrophic failure of the World Trade Center towers on September 11th. As the BBC explains, the 800°C fires were hot enough to weaken the steel to the point where the weight of the towers could not be borne. While I wouldn’t endorse the entirety of the post, I do think the point about the alleged climate change conspiracy is well made.
I have my own theories about why people either:
Why do readers of this blog believe that both stances are so prevalent, at a time when the key science behind climate change is well understood?
I have commented before on the incoherence of how the United Kingdom plans to both cut greenhouse gas emissions and increase airport capacity. The December 8th report from the Committee on Climate Change perpetuates this mis-match, saying that the third runway for Heathrow could be compatible with government emission reduction targets, provided the price of carbon reaches £200 per tonne by 2050.
To me, this view is rather perplexing. Why build a runway, then use taxes to choke off the demand for it? Either your taxes won’t prevent the flights, making it harder to reach your carbon targets, or they will and your investment in the runway and supporting facilities will be a waste. The committee also assumes that aircraft engine efficiency will improve by 0.8-1.5% per year, that biofuels that don’t compete with food crops will emerge, and that high speed rail will displace a lot of short-haul flights in Europe. To take advantage of assumptions about the future to defend a dubious current policy is a practice all too common. Rather than pretending they can have it both ways, the UK should acknowledge that achieving its climate change goals will require reducing incredibly emissions-intensive activities like air travel.
Thankfully, the British Conservative Party – which is likely to take power with the next election – continues to oppose construction of the runway, precisely because it clashes with climate change objectives.
Bill Streever’s book takes a meandering and often macabre journey through various facts and stories about the world’s chilled regions: discussing everything from ground squirrel hibernation to the fatalities that resulted from the Schoolchildren’s Blizzard of 1888. While it contains a lot of highly interesting information, the book’s non-linear structure is distracting and contributes to its repetitiveness. Had Streever stuck to a conventional structure with chapters focused on different topics, the result would probably have been better.
Streever is at his best when discussing the human suffering brought on by cold, and the ingenious ways by which animals have learned to survive in it. The story of the Arctic caterpillars that freeze solid every winter, and take ten years to eat enough to undergo metamorphosis, is a poignant one. So too are Streever’s excellent descriptions of snow and feathers as insulating materials, as well as frostbite and hypothermia as unwanted consequences of extreme cold. The book has an entertaining habit of pointing out odd coincidences. For instance, readers will discover what a certain volcanic eruption has to do with Mary Shelley’s Frankenstein, Mormonism, and the invention of the bicycle.
Cold gives a fairly cursory treatment of climate change: mentioning it fairly often, but not getting into great detail. Streever takes it as a given that human greenhouse gas emissions will forever and substantially alter the world’s frozen places, and does not devote any time or attention to the kind of actions humanity could take if it wished to preserve the polar ice caps, glaciers, etc. The author acknowledges how his own jet-setting lifestyle is contributing to the destruction of the places that interest him so, but never takes time to really contemplate alternative behaviour for himself or humanity as a whole.
All told, Cold is well worth the couple of hours it takes to read. While some judicious editing would have been welcome, Streever’s book does manage to convey an appropriate sense of both curiosity and visceral dread about the importance that cold has played in our warming world.
